I would have posted this over at the experimenters forum but for some reason I can not attach there.
Anyway I am wanting to build a petersburg type stove around this rock wall in my apt. My thought was to make use of all this nice mass to collect the heat. But....
1) The rocks are sandstone, are they too fragile, do I need to coat them with something before integrating them into fireplace.
2) Is it possible to incorporate an oven chamber into the bell area?
My plan was to build the firebox portion on the short side going around to the tall side for the bell.
Any thoughts. thanks sandy

What is behind the nice mass? How thick is it? How many psf (pounds/square foot) is the floor built for?

Behind the rock wall is 1/2" backerboard and 2x4 frame reinforced with cross pieces.
Underneath is standard 1.25 subfloor over 2x12 joist and supported undereath by a 5x10 steel I beam.
I have no idea what the load capacity is, but I would gennerally perfer to keep things as light as possible with the exception of that rock wall already in place.

So what are you trying to do? Heat a space (how much space and what climate/region?) once in a while with this stove or continuously? I guess I'm confused by you wanting to keep it as light as possible. To determine the load capacity of your floor you need to know the spans of the 2x12's and their spacing between as well as for the I beam and what that rests on.

Climate is mild, Houston, texas. The size in approximately1200 sq. ft. I want to get rid of my gas driven heating because I am trying to get off grid. Gas heaters consume too much power to blow air around, and do not have a good quality of heat.
Light as possible is because the unit is on the story. The beam is supported by 10x10 wood columns 10 ft down with cement piers.
The wall has been in place for about 5 years with no signs of load problems.
So it seems it would be nice to make use of the mass in place.
